What is Psoriasis: signs and symptoms, diagnosis, treatment.

Psoriasis is a chronic skin disorder that causes cells to build up rapidly on the surface of the skin, forming thick, scaly patches. Common signs and symptoms of psoriasis include red patches of skin, scaling, itching, burning, and soreness. In some cases, the patches may crack, bleed, and produce a discharge. In more severe cases, psoriasis can cause the skin to thicken and form raised plaques.

Diagnosis of psoriasis is based on a physical examination and the patient's medical history. The diagnosis may also involve a skin biopsy, in which a sample of skin is taken and examined under a microscope. Treatment of psoriasis may include topical medications, such as corticosteroids, vitamin D analogues, or retinoids, as well as systemic medications, such as methotrexate, cyclosporine, or biologic agents.
